Postal and Face-to-Face Administration of Stroke Outcome Measures

Clinical Trials Saturday, December 1st, 2012

AHA: 11/20/12

Background and Purpose—Different modes of administration are used to collect stroke outcomes, even within the same study, potentially leading to different results. We investigated the effect of administration mode (postal questionnaire; face-to-face interview) on self-reports of activities of daily living and mood.

Methods—The study was nested within a poststroke motivational interviewing trial. Activities of daily living (Barthel; Nottingham Extended) and mood (General Health Questionnaire; Yale) were collected at 3 and 12 months via postal questionnaire. Participants were approached to respond again via face-to-face interview. Paired t tests (McNemar test) and intraclass correlation coefficients (Cohen κ) were used, with 95% CI, to compare scores (items). Read more
